My friends, I want to place a command in the code below to add the "TDI" indicator on the chart when the click is done.
How to add the code to the following code?

//.......................................
   if (id == CHARTEVENT_OBJECT_CLICK) {
      string clickedChartObject = sparam;
      if (clickedChartObject == obj_name[4]) {
         string name = "name_" ;
     
      
  
 

 
 
       
      }
   }

Please show your code if you want help.

It takes the indicator handle to add the indicator to the chart.

Thanks @Georgiy Liashchenko it's working great! Is there a way to load the set file or the settings that I want?

Then how do you know that it is working?
